Specification of Letters intent.

Patented Man. 13, 1917.

Application flied January 18, 1915. Serial No. 2,514.

and State of New York, have invented certain. new and usefulImprovements 1n Pocket Flash-Lights, of which the followingv is aspecification.

The invention pertains more particularly to flush lights adapted to becarried in the upper vest pocket without inconvenience and in the samemanner that a fountain pen is carried.

The flash light of my invention is provided with a spring clip or memberadapted, when the flash light is placed in the upper vest pocket, toembrace betweenitself and the side of the case of the article, thethickne& of the material of the vest at the outer side of'said pocket,the flash light being thereby held securely.

Thefpresent invention resides more particularly in the structure of thecasing and in the electric circuit closer features. In

the present instance a manually operative contact is rigid. with theexterior casing and has a portion to be pressed inwardly through saidcasing for engaging a conductor connected with the battery, thereby tocomplete the circuit, and this conductor is preferably in the form of asleeve closely fitting within but insulated from the exterior casing andin an electrical engagement with a spring which engages one end of theand is insulated from the exterior Therigid manually operative contactor i 1" switch is preferablyformed of a spring clip which I utilize asthe means for securing theflash light within the upper vest pocket, andthe-ball-zend of .this spring clip .whenjpresed inwardly through a,:holein the side 01 t main casing against the interior conductor, will letsthe circuit and the lain will-remain, ighted so long as the spring c ipis held inwardly. There are 7 times, however, I when a permanent lightfor a definite period is desired, as whenfa physician s, with the useof. the light, examine in addition to the e andbreakmanuaHy ,0 erativeswitch formed from. the spring c ip, I provide a further or auxiliarycircuit closer which is slidable and when inf-one position performs nonecessary function and atient, and therefore switch a projectlng partwhich may pass I through a hole in the exterior casing to engage theinterior conductor when it is desired that the circuit shall becompleted.

I preferably constiuct the barrel or exterior casing of the flash lightto resemble in appearance a fountain pen, said casing being composedmainly of two parts secured together by bayonet joints.

The present invertion embraces certain improvements on the flash lightmade the subject of Patent 1,l82,965, May 16, 1916, to Bernard Benedict.

The invention Wiil be fully understood from the detailed descriptionhereinafter presented, reference being had to the accompanying drawings,in which:

. 111 sewi g 1 5. elong d form-l enlarged scale, through the same, takenon through the and meant to imitate, as fas as convenient, theappearance of a fountain pen. The was ing 10 will. preferably be ofmetal and at one end carnes a lamp 11 and reflector 12 therefor. Thecasing 10 is shown as made in two sections 13, 1 1 which with slightexception are the same in construction and mode of connection asthecasingsectlons shown in the aforasaid patent of Bernard Benedict. Thereflector 12 is formed at its outer edge with a shoulder 15 toengage theouter edge of the casing section 13, and said reflector hasa threadedneck 16 to receive the socket 17 of the lamp in a customaryll'lillllltll'.

The lamp I1 is of usualcharacter and has one terminal 18 in engagement,as usual, with one pole of the battery it), The battery i!) willcustomarily be formed of two cells in end to end relation and coveredaround their sides by paper or other nonczo-nducting material, in thecustomary mannor.

The handle section 11 of the main casing is sonu-what greater indiameter than the section 1 and said section 1-4 is lined by a sleeve 20tr rum-conducting material such as paper, and'within the non-conductingsleeve til) is a metal sleeve 21. The battery i!) has one end portionwithin the sleeve 21, and said portion oi the battery at its end ispressed against by a coiled spring 22 which is a conductor and has oneor more coils in electrical engagement with the sleeve 21. The sleeve 21is insulated from the metal casing section 14 by means of the sleeve 20,and also by means. of a disk of paper or the like 23 iittcd within theclosed end of the section 14 and cngag-ing the adjacent edges of thesleeve 20. /Vithin the outer end of the sleeve 21 is placed a seconddisk; which nu'nihcr 'l-l. oi paper or the like, the disk 24 being inface to fa e contact with the disk 23 and receiving the outer end of thespring 22. It will-he seen that-the disks 23, 24 and the sleeve 2)insulate the contact sleeve 21 from the calmi g section '14, and thatthe cir' cuit from the-outenend of the battery 19 will be from thebattery to the spring 22 and thence to the slheve 21. The non-conductingsleeve 20 is formed with two apertures or holes '25, 2G, and theseapertures are in line with corresponding apertures 27, 28 formed in thecasing section 14 and expose at said aperture 27, 28 small' .)ortio nsof the conducting sleeve 21, The-electricalconnection .of-l-he outercasing of the lash light with the sleeve 21. to complete the circuit ismade either at the "apertures 27,- 25 or at the aper ture's 38, 26, andin the present instance I utilize a spring clip 29'as one circuitcloser, said clip being secured by rivetsto the eas- -ing section 14 orotherwise suitably connect ed with said casing so as to be in electricalengagement or connection therewith. On

the outer end of the spring clip 29 is a ball or enlargement 30 adaptedby the pressure of the thumb applied thereon to be movedg on the flexingof the spring 29, inwardly minal 1.8 is in electrical engagement withthe forward end-of the battery, as usual. The

utilization of the spring clip 29 in connection with the openings 27, 25and sleeve 21 is disclosed in the aforesaid Paterrt 1,182,965 and isnot,therefore, specially claimed here in. In lighting the lamp with thespring clip or circuit closer 29, the hall 30 is pressed inwardlyagainst the sleeve 21 and thelamp remains lighted so long as pressure ismain- ,tained on said ball holding it against the sleeve 21. It isdesirable in many instances that the circuit in a flash light should remain closed for a definite period and that the hand may be relievedfrom'th'e duty of holding the closer or switch in operative posi tion,and hence-in accordance with my invention I provide an auxiliary circuitcloser or switch3l' which is preferably in the form of i1 strip ofspring metal secured to a head 32, which I preferably mo'unton thecircuit closer or spring clip 29, said head having a neck portion 33extended through a guide slot 34- in the circuit closcr'29, and thecloser or switch 31 heiilg secured to the end of said neck behind thecloser or spring clip 25). The switch or closer 31 is substantiallyconcealed hehiml the spring clip or closer 29 and the head connectedtherewith is in iine'with and slidahle on the closer or clip 29 the"HH'QHW-llt of said head 32 from the position in which it is shown inFig. 2 carryingthe switch 31 from its inoperative position to itsoperative position illustrated in Fig. 8. The switch 31 is formed at itsfree end-"with an inward indentation or projection 35 which is adaptedto the openings 28,

- 26 when said switch is in its operative position and to a recess 36formed in the casing sectionltwhen said switch is in its inoperativeposition. WVhen the switch 31 is in its inoperative position theprojection 35 thereon rests within the recess 36 and against the sideotthe non-conducting sleeve 20, andwhen by means of the head 32 theswitch 31 iscaused to slide to its operativepo sition, the projection 35thereof wil l-=move"from said recess 36 into the openings 28, 26. andengage the conducting. sleeve 21, thereby completing-the circuit andcausing the lamp to light. After the switch 31 has been moved to itsoperativeposition the pressure ressure of the thum ect the retraction ofthe switch 31 to its in-- opening 26 in the sleeve 32,since saidswitchwill remain in its oper ative position until manually retractedIpressure of the' move the switchosition and a reverse therefrom. Aforward 1 thumb on the head 32 wil 31 to its operative on saidhead'willefoperative position. The'mner endoi the projection 35, isrounded so that the same may conveniently ride :into and'from the Thenovel features of the present invention in comparison with the,aforesaidPatr ent 1,182,965 reside in the circuit closer featux-eshe'reinbeforedescribed and'particularly in the'provision of, the circuitcloser 31 and parts coiiperatingtherewith.

In the use of the flash light the circuit may be made by'pressing thefree end of its operative position When, the freefend openin theconductor 21 or tfi:

In the use of either circuit closer the circuit is from thesleeve 21 to the clip 29 and thence to and through the exterior casing.of the flash light, the switch 31 being in electrical-0on nection withsaid clip.
